对环境和经济问题的关注推动了支持小型发电机靠近配电网的发展，即分布式发电（DG）。在少量接入时，DG对电力系统暂态稳定的影响可以忽略不计，但当DG的接入量增加时，其影响不再局限于配电网，而是开始影响整个系统，包括输电系统的暂态稳定。本文研究了在所有可能的支路都存在故障时输电系统的暂态稳定性问题（关于N-1安全分析）。在本研究中，通过两种方式提高DG实施的渗透水平：(1)通过DG实施（以恒定的集中发电）或增加CG输出来覆盖负荷增加，(2)通过DG实施（以恒定的负荷）来覆盖集中发电的减少。
Concerns on environmental and economical issues drive the increasing developments that support small scale generators to be connected close to distribution networks, i.e. distributed generation (DG). When connected in small amounts, the impact of DG on the power system transient stability will be negligible, however, when the penetration of DG increases, its impact is no longer restricted to the distribution network but starts to influence the whole system, including the transmission system transient stability. In this paper, the transmission system transient stability is investigated when a fault is applied in all possible branches (regarding the N-1 security analysis). In this studie the penetration level of DG implementation is raised in two ways: (1) a load increase is covered by DG implementation (with a constant centralized generation) or increased CG output, and (2) a reduction of centralized generation is covered by DG (with a constant load).
